Can Botox Cause Jowls Or Facial Sagging? What You Should Know in 2026
Can Botox cause jowls or facial sagging? Not directly in most people — but reducing masseter bulk can occasionally unmask existing laxity in susceptible patients. RE:BERRY Hongdae gives an honest, nuanced 60-90 minute review from ₩19,000 (about $14) with Dr. Jae-Hong Kim, covering who is at risk and how careful dosing prevents it, directly connected to Hongik University Station via AREX.
So, can Botox cause jowls or facial sagging? The honest answer is nuanced rather than a flat yes or no. Botox (botulinum toxin type A) does not directly create jowls in most people, but in masseter (jaw-slimming) treatment it reduces the bulk of the masseter muscle over repeated sessions, and because the masseter also provides structural support to the lower face, reducing that support too quickly can, in some patients, make pre-existing skin laxity more visible. This is an unmasking of laxity that was already present, not a direct cause of new sagging — an important distinction many pages skip. The unmasking effect is uncommon and more likely in patients who already have early laxity, thinner skin, or a naturally slimmer face, and less likely in younger patients with good elasticity. There is another side to the anatomy: selectively relaxing downward-pulling muscles such as the platysma, which tugs the jawline downward, can actually help rebalance lower-face tension rather than worsen it. Careful dosing, precise placement, and experienced injection make an unwanted outcome largely preventable, and because Botox is temporary, muscle bulk and support return as the toxin wears off over the following months. Located in Mapo-gu’s Hongdae district — Seoul’s youth-culture and design hub — RE:BERRY Hongdae frames jaw and facial balance around a natural, refined result rather than an overdone one. The clinic sits directly above Hongik University Station, which connects to the AREX airport express, so travelers ride from Incheon Airport T1 or T2 to our door with no line transfer. Dr. Jae-Hong Kim runs 60-90 minute English consultations, far longer than Korea’s 4.3-minute national average, with 8-language support and WhatsApp follow-up, and will honestly assess your skin laxity and elasticity before recommending masseter Botox, alongside related options such as wrinkle Botox, so ‘can Botox cause jowls or facial sagging?’ is answered for your specific face.

Can Botox Cause Jowls Or Facial Sagging? — Why RE:BERRY Hongdae Assesses First
How RE:BERRY Hongdae Answers ‘Can Botox Cause Jowls Or Facial Sagging?’
Step 1: 60-90 Minute Skin-Laxity and Elasticity Assessment
Dr. Jae-Hong Kim spends 60-90 minutes — far above Korea’s 4.3-minute average — assessing your skin laxity, thickness, and elasticity, the 3 factors that decide whether masseter Botox could unmask sagging. Answering ‘can Botox cause jowls or facial sagging?’ honestly starts with your individual anatomy.
Step 2: Explaining Masseter Support and Platysma Balance
Dr. Kim explains how the masseter supports the lower face and how the platysma pulls the jawline down. Reducing masseter bulk too fast can unmask laxity in about the minority of susceptible patients, while selectively relaxing the platysma can rebalance tension — the anatomy behind the concern.
Step 3: Conservative, Staged Dosing
If masseter Botox suits you, Dr. Kim uses conservative dosing across 2 or more staged sessions rather than a single large reduction, giving the skin time to adapt. The 5-10 minute injection uses precise placement to slim the jaw while minimizing any chance of unmasking laxity.
Step 4: Honest Alternatives and Follow-Up
For patients with significant existing laxity, Dr. Kim may recommend skin-tightening options or staged treatment instead of aggressive slimming. Board the AREX at Hongik University Station below for the 60-minute ride to Incheon Airport, with WhatsApp follow-up over 4 weeks to monitor the gradual result honestly.

- A Nuanced Answer, Not a Flat Yes/No RE:BERRY Hongdae gives 1 honest, nuanced answer: masseter Botox does not directly cause jowls, but can unmask existing laxity in susceptible patients. Understanding this distinction up front means you weigh the real, uncommon risk rather than a misleading absolute claim.
- Risk Stratification for Your Face The unmasking effect is more likely with early laxity, thinner skin, or a slimmer face, and less likely in younger patients with good elasticity. RE:BERRY Hongdae assesses these 3 factors so your risk is judged individually, not assumed from a one-size marketing message.
- Same-Doctor Continuity Dr. Jae-Hong Kim handles your assessment personally. KHIDI 2025 data shows 41.4% of international patients rank same-doctor continuity as their number 1 clinic selection priority when choosing a Korean clinic, and RE:BERRY holds that continuity through 4 weeks of follow-up.

| Timeline | What to Expect |
|---|---|
| Day 0 | The masseter Botox injection takes about 5-10 minutes with essentially no downtime; minor redness or small bumps may appear briefly. |
| 2-6 weeks | Jaw slimming develops gradually over several weeks as masseter bulk reduces; there is no sudden change. |
| Susceptible patients | In the minority with early laxity, thinner skin, or a slimmer face, reduced masseter support can make existing laxity more visible during this period. |
| A few months | Results last on the order of a few months; as the toxin wears off, masseter bulk and lower-face support gradually return. |
| Staged option | Conservative, staged dosing across 2 or more sessions lets the skin adapt and lowers the chance of unmasking laxity. |
| Decision point | An honest laxity assessment from ₩19,000 (about $14) before treatment is the safest way to answer this for your face. |
Can Botox Cause Jowls Or Facial Sagging? Masseter Botox Risk Overview
| Factor | Masseter Botox (careful) | Aggressive / Unassessed Dosing | Source |
|---|---|---|---|
| Direct cause of jowls | No — does not directly create jowls | Same, but higher unmasking risk if laxity ignored | Peer-reviewed literature |
| Unmasking laxity | Uncommon; minimized by assessment | More likely if existing laxity is overlooked | Xie 2014; peer-reviewed literature |
| Higher-risk patients | Screened: early laxity, thin skin, slim face | Not screened, so risk is missed | Clinical guidance |
| Dosing approach | Conservative, staged across 2+ sessions | Single large reduction | Peer-reviewed literature |
| Reversibility | Temporary; support returns as toxin wears off | Same, but poor outcome may distress longer | Peer-reviewed literature |
| Platysma balance | Can rebalance downward-pulling muscles | Ignored, missing a refinement tool | Levy 2007; peer-reviewed literature |
| Best handled by | Experienced injector after honest assessment | Volume-driven, sales-led injection | Clinical guidance |
Why This Matters
The heart of ‘can Botox cause jowls or facial sagging?’ is honest risk stratification: masseter Botox does not directly cause jowls but can unmask laxity in susceptible patients. RE:BERRY Hongdae frames the choice around your skin quality and evidence rather than a reassuring absolute.
Doctor continuity affects how carefully laxity is judged. According to KHIDI’s 2025 Medical Tourism Survey, 41.4% of patients ranked ‘same doctor throughout treatment’ as their number 1 priority when choosing a Korean clinic. Dr. Jae-Hong Kim handles the assessment himself at RE:BERRY Hongdae.
Korea’s average outpatient consultation is 4.3 minutes — the shortest in the OECD, whose average is 16.4 minutes. RE:BERRY’s 60-90 minute consultations are far longer, so ‘can Botox cause jowls or facial sagging?’ gets a full laxity assessment rather than a rushed sale.

SCIENTIFIC EVIDENCE Behind Masseter Botox and Facial Support
How Masseter Botox Slims the Jaw
Masseter reduction with botulinum toxin is a well-documented clinical application. Xie et al. (2014) reviewed botulinum toxin for masseter hypertrophy and reported reliable reduction in muscle bulk over repeated sessions, with effect developing over several weeks. This peer-reviewed evidence explains why ‘can Botox cause jowls or facial sagging?’ has a nuanced answer: the treatment reduces the very muscle that also lends structural support to the lower face, so the outcome depends on individual skin quality, not the drug alone.
Why Unmasking Happens and Who Is at Risk
The masseter contributes to lower-face volume and support, and reducing it can, in a minority of patients, make pre-existing skin laxity more apparent. Clinical reviews note that patients with early laxity, thinner skin, or naturally slimmer faces are at higher risk, while younger patients with good elasticity are at lower risk — a stratification supported by aesthetic consensus guidance such as Sundaram et al. (2016), which stresses patient selection and conservative dosing to avoid unwanted lower-face changes.
The platysma adds another lever. Levy (2007) described the Nefertiti lift, in which selectively relaxing the platysma — a muscle that pulls the jawline downward — improves jawline definition. This shows that thoughtfully placed toxin can rebalance rather than worsen the lower face, so an experienced injector treating 1 patient uses both masseter and platysma dynamics to protect the jawline instead of simply removing bulk.
Korean clinical data is directly relevant to Asian jaw anatomy. Korean literature such as Kim et al. (2010) in the Korean Journal of Dermatology reports on botulinum toxin for masseter hypertrophy in Korean patients, where masseter prominence is common, reinforcing why RE:BERRY assesses each face individually before answering ‘can Botox cause jowls or facial sagging?’.

Is masseter Botox cheaper or better value in Korea than Western clinics?
RE:BERRY Hongdae publishes 1 transparent price and gives honest risk information. Korean clinics run higher masseter Botox volume than most Western markets, giving injectors more experience with Asian jaw anatomy, which matters more than any single number — see the risk overview comparing careful versus aggressive dosing.
Does masseter jaw-slimming Botox actually cause jowls?
RE:BERRY Hongdae reports 0 direct causation in most people — masseter Botox does not create jowls, but reducing support too fast can unmask existing laxity in a minority. Korean injectors handle higher masseter volume than most markets, giving more experience with this nuance, and Dr. Kim assesses your risk — see the risk overview.
| Scenario | Effect |
|---|---|
| Good elasticity | Slims jaw, no sagging |
| Existing laxity | Can unmask sagging |
Who is most at risk of unmasking sagging after masseter Botox?
RE:BERRY Hongdae reports 3 higher-risk profiles: patients with early laxity, thinner skin, or a naturally slimmer face, while younger patients with good elasticity are lower-risk. Dr. Kim screens these before treating.
| Profile | Risk |
|---|---|
| Young, elastic skin | Lower |
| Thin skin / laxity | Higher |
How does the masseter muscle support the lower face?
RE:BERRY Hongdae reports the masseter adds bulk and structural support to the lower face, so reducing it over 2 or more sessions slims the jaw but removes some support. In the minority with existing laxity, that can unmask sagging, which is why Dr. Kim explains the anatomy in every assessment before treating.
Can an injector reduce the risk of jowls from jaw Botox?
RE:BERRY Hongdae reports yes — 3 key tools: careful patient selection, conservative dosing, and staged treatment across 2 or more sessions so the skin adapts. Selectively relaxing the platysma can also rebalance the jawline. Experienced injection makes an unwanted outcome largely preventable, as Dr. Kim details openly.
Why choose a boutique clinic over a chain for masseter Botox?
RE:BERRY Hongdae gives every inquiry a 60-90 minute consultation versus the 10-15 minutes typical at chains. Korean boutique clinics offer more doctor time and honest laxity screening than most volume-driven chains.
| Feature | RE:BERRY | Chain |
|---|---|---|
| Consult | 60-90 min | 10-15 min |
| Laxity screening | Yes | Often skipped |
Is Botox-related jowling permanent and does it improve over time?
RE:BERRY Hongdae reports 0 permanence — Botox is temporary, so masseter bulk and lower-face support gradually return as the toxin wears off over a few months. Any unmasked laxity typically eases as support returns, which Dr. Kim explains honestly rather than implying either a permanent problem or a permanent slimming result.
Can I get masseter Botox as a tourist on a short Seoul trip?
RE:BERRY Hongdae reports yes — the 5-10 minute injection has essentially 0 downtime, so it fits a short trip, though jaw slimming develops over several weeks afterward. Hongik University Station links to AREX, a 60-minute ride to Incheon Airport, and Seoul injectors handle more cases than most countries, with WhatsApp follow-up over 4 weeks.
Who should not get masseter Botox and what are the contraindications?
RE:BERRY Hongdae reports 6 main contraindications: neuromuscular disorders, botulinum toxin allergy, active infection at injection sites, pregnancy, significant pre-existing lower-face laxity, and unrealistic expectations of a lifting effect. Dr. Kim reviews these honestly and may suggest skin-tightening options instead for higher-risk patients.
How do I find an experienced injector for jaw Botox in Korea?
RE:BERRY Hongdae reports a 4-point check: confirm the physician’s Korean MOHW license number, confirm the clinic registration, confirm the doctor performs the injection personally, and ask how they screen for laxity. Korean clinics run higher masseter volume than most markets, giving more experience, and Dr. Kim answers each point openly — see the risk overview.
